我们于１９９１年１１月～１９９２年８月，对济南部队驻地部分地区健康人群进行了旋毛虫病血清流行病学调查。其中对平顶山市进行了重点调查，查明该市健康人群旋毛虫隐性感染率为４．６０％；不同年龄、性别人群旋毛虫抗体阳性率无显著差别（Ｐ＞０．０５）；但居住于远市区人群的阳性率明显高于近市区（Ｐ＜０．０１）。 From November 1991 to August 1992, we conducted a serological epidemiological survey of Trichinellosis in healthy population in some areas of the Jinan military unit. Among them, the key survey was conducted in Pingdingshan City, and the latent infection rate of Trichinella spiralis in healthy population of the city was 4.60%. There was no significant difference (P> 0.05) in the positive rate of Trichinella antibodies in different age and sex groups; however, The positive rate in Yuyuan urban area was significantly higher than that in the near urban area (P <0.01).
